Question

what do you understand by A)allotropyb)inert pair effect c) catenetion.​

Answer 1

Answer:

allotropy: the existence of two or more different physical forms of a chemical element.(mostly of carbon)

inert pair effect: The inert-pair effect is the tendency of the two electrons in the outermost atomic s-orbital to remain unshared in compounds of post-transition metals.

catenation: catenation is the bonding of atoms of carbon into a series, called a chain. A chain or a ring shape may be open if its ends are not bonded to each other (an open-chain compound), or closed if they are bonded in a ring (a cyclic compound).
